How all these legal proceedings shake out could have an enormous impact. A little more than half of the nation’s 44.5 million immigrants are not U.S. citizens. Of those non-citizens, a little more than half have visas or green cards that allow them to reside in the U.S. legally, and about 11 million of them are undocumented. But demographers worry that any U.S. household with at least one person who’s not a citizen will be less likely to participate in the census because of fears of deportation—even though the census doesn’t identify individual respondents.
Overall, 14 percent of U.S. residents live in households that include one or more people who aren’t citizens. That figure rises sharply if you look at specific minority groups: Almost half of Hispanics and Asians—46 percent and 45 percent, respectively—live in households with at least one noncitizen.
This year, the lawsuit says, immigrants’ fears over the census have been heightened: “Those concerns have been amplified by the anti-immigrant policies, actions, and rhetoric targeting immigrant communities from President Trump and this administration,” the lawsuit says.
President Trump has made a crackdown on illegal immigration the centerpiece of his presidency. The fight over Trump’s plan to build a wall on the border with Mexico prompted a shutdown of the federal government in December. Trump has stepped up arrests and deportations of undocumented immigrants, he’s drastically reduced the number of refugees allowed into the country, and he’s proposed tighter restrictions on legal immigration. The policies, Trump says, are aimed at keeping Americans safe and protecting U.S. jobs.
Because immigrants are concentrated in large states like New York and California, the effect of undercounting them would be to dilute the power of the country’s most populous states, says William Frey, a demographer at the Brookings Institution, a liberal think tank in Washington, D.C. If 15 percent of noncitizens go uncounted, that would be enough to cost California and New York one congressional seat and one electoral vote each, to the likely benefit of Colorado and Montana, Frey says.
Democrats say what’s really going on is an attempt by Republicans to increase their power by fudging the numbers.
“This is a brazen attempt by the Trump administration to cheat on the census, to undermine the accuracy of the census and to attack states that have large immigrant populations—states, most of which just happen to be Democratic states,” says Congressman Jerrold Nadler, Democrat of New York.
